A visitor's Covid-19 Green Pass is checked at the entrance to a restaurant in Rome, Italy, 09 August 2021. Effective from 06 August, the so-called Green Pass is advocated by the government as the alternative to lockdowns in the light of the spreading Delta variant of the Sars-Cov-2 pandemic coronavirus. People who do not hold the certificate that identifies them as either immunised, recovered or tested for Covid-19 may be excluded from indoor venues and for access to amusement parks it is necessary to be up to date with anti-covid-19 vaccinations, or have a negative swab in the last 48 hours.
